Water is stored behind a sluice gate to a depth of 10 fr. The channel is rectangular with a width of 15 fr. The contraction coefficient for the gate is 0.60. a. If the specific discharge (q) through the gate is 20 cfs/ft, what two different gate openings would allow for this? 6. Which of these two possibilities is more reasonable?
